(a) Improperly Filed Cases. In the event that the notice of appeal is filed in the wrong appellate court, the appellate court in which the matter is filed shall issue an order transferring the case to the appropriate appellate court.

(b) Certification by Supreme Court. In any case which is pending before the Court of Appeals, the Supreme Court may, in its discretion, on motion of any party to the case, on request by the Court of Appeals, or on its own motion, certify the case for review by the Supreme Court before it has been determined by the Court of Appeals. Certification is normally appropriate where the case involves an issue of significant public interest or a legal principle of major importance. The effect of such certification shall be to transfer jurisdiction over the case to the Supreme Court for all purposes.
